Color

The color rule sets the text color of a widget.

Syntax

color: (<COLOR> | auto) [<PERCENTAGE>];

Use auto to automatically choose a color with suitable contrast for readability.

--8<-- "docs/styles/snippets/color_css_syntax.md"

The optional percentage sets the transparency level.

Examples

This example sets a different text color for each of three different widgets.

=== "color.py"

```python
--8<-- "docs/examples/styles/color.py"
```

=== "color.css"

```css
--8<-- "docs/examples/styles/color.css"
```

=== "Output"

```{.textual path="docs/examples/styles/color.py"}
```

The next example shows how auto chooses between a lighter or a darker text color to increase the contrast and improve readability.

=== "color_auto.py"

```py
--8<-- "docs/examples/styles/color_auto.py"
```

=== "color_auto.css"

```css hl_lines="2"
--8<-- "docs/examples/styles/color_auto.css"
```

=== "Output"

```{.textual path="docs/examples/styles/color_auto.py"}
```

CSS

/* Blue text */
color: blue;

/* 20% red text */
color: red 20%;

/* RGB color */
color: rgb(100,120,200);

/* Automatically choose color with suitable contrast for readability */
color: auto;

Python

You can use the same syntax as CSS, or explicitly set a Color object.

# Set blue text
widget.styles.color = "blue"

from textual.color import Color
# Set with a color object
widget.styles.color = Color.parse("pink")
